Technical Field

[0001] The invention belongs to the technical field of mold production, and in particular relates to a mold anti-slip mechanism and method for a mold turning machine. Background Art

[0002] Mold manufacturing is an indispensable and important part of modern industrial production, especially in the fields of automobiles, electronics, aviation, etc. The precision and stability of molds are directly related to the quality and production efficiency of products. As a key equipment in the mold manufacturing and maintenance process, the mold turning machine transports the mold from the workbench to the mold turning machine for mold turning after the mold trial is completed in the mold press, and the mold is inspected and repaired.

[0003] Traditional mold turning machines generally fix the mold on the flipping slide of the mold turning machine through the pressure plate bolts. However, during the mold flipping process, due to the heavy weight and complex shape of the mold, as well as the dynamic load caused by the flipping action, the fixing method that only relies on the pressure plate bolts has certain limitations. In addition, due to the uneven tightening force of the bolts or the looseness of the bolts themselves, the mold can easily slip or even fall, causing safety accidents. Existing anti-skid measures usually require manual tightening with a top screw to press against the end face of the mold to achieve the function of preventing skidding. However, manual tightening and adjustment of the bolts is time-consuming and labor-intensive, and due to the uncertainty of manual operation, it is difficult to ensure the consistency and reliability of each operation.

The slide 8 can effectively resist the mold to prevent the mold from sliding sideways. When the anti-skid mechanism does not need to work, the motor 4 reverses and the slide 8 retreats. The proximity switch 91 on the bracket 61 is used to detect whether the slide 8 is in place when returning.
